INKtober Day 10

I wanted to try this tangle, so I did it as a monotangle (one tangle on the tile).  It is called On Target, by CZT Barbara Finwall.  I didn't realize until now, when I posted it here, that I didn't shade it!  It had so much optical illusion going on that I forgot that part.  I am not sure if it even needs it, or if it would enhance or take away from it.  I need to ponder that awhile.  Let me know what you think!
